I’m thinking of adding some corals to my 29 gallon tank. I currently have an Ocellaris clown, a Mocha Vinci clown, a yellow clown goby, and a few other small saltwater fish. I currently have a hang on the back filter, and I know I need to get a sump, but I am not sure of all the equipment I need. I was thinking a 10 gallon sump would be good? If anyone has specific ideas for equipment, please let me know, and thanks!
